First External Battery with Qualcomm Quick Charge 3.0 technology: Charge up to 80% of the battery for QC 2.0/3.0 compatible devices when charging for approximately 35 minutes. QC 3.0 is compatible with USB, QC 2.0, & 1.0; and can deliver twice the charging speed of QC 1.0

3.0 Is Just Better Than 2.0: Compared to QC 2.0, QC 3.0 has 15% greater charging efficiency, charges up to 27% faster, and reduces power consumption by up to 45%.

Type-C Input and Output: The first ever external battery charger with USB-C/Type-C. Use it to quickly recharge the 20100mah external battery, or to power the latest computers and smart devices with USB-C/Type-C ports

Huge Capacity & Rapid Recharge: 20100mAh charges an iPhone 6S & 6 almost 8 times, a Galaxy S6 almost 5 times or an iPad Air more than once; recharge takes only 4.5 hours with a Qualcomm Quick Charge 3.0 USB Charger; an input of 5V/2A means that it still charges faster than normal USB chargers even without Qualcomm compatibility
